To all whom it may concern:

Be it known that T, HERBERT ABRA AM, a citizen of the United States, residing at the city, county, and State of New York, have invented certain new and useful Tmprovements in Shingle Strips, of which the following is a specification.

This invention relates to improvements in prepared roofing shingle strips having alter- Nl natmg projections and indentations along lll Ell

their lower edges, which strips when laid in overlapping courses form a roofing having the appearance of a plurality of individual shingles.

The objects of the invention are to provide strips of this character which are constructed to be laid in interlocked relation with the butts of each strip held down in such manner as to prevent their being accidentally pulled or slipped out of place but to permit of ex ansion or contraction without buckling. y improved strips may be. laid either with the butts flat, or bent in hook-form as described in my copending a plication Serial No. 73,136, filed May 2 M921,

T attain these objects, as well as others not specifically stated, by means of the novel features t construction hereinafter described and illustrated in the accompanying drawings, which show a preferred form and in which Figure 1, is a plan view of one of my 7 improved strips;

Fig. 2 is a plan view of a section of a rooting composed of my improved strips,

Fig. 3 is a section of a roofing laid with strips having their butts-bent in hook-term;

Fig. l is a rear plan view of one of the strips showing the butts bent in hook-form;

Fig. is a section on the line 5-5 of Fig.

5; and

Fig. 6 is a plan view ot a sheet of roofing material with the lines of cutting for torming the strips indicated thereon.

The strips each comprise a body portion 1 having parallel straight edges, the up er edge 2 being intact. and the lower edge eing broken, at equidistant points, by indentations or recesses 3 to leave integral pro: jecting portions, which are similar in size and shape to the indentations but reversed a in position. The projections each comprise two mutually preferably of trapezoidal shape, as

described may be Formed without similar symmetrical portions shown, disposed one above the other, and with the narrow end of the upper portion 4L joined to the wide end of the lower portion 5.

The strips may be of any desired length so as to include any desired number of projections. As shown in the drawings each strip is formed with two projections. The strips are intended to be laid end to end in a row to form-a course and to have similar courses superposed successively thereon in overlapping relation.

The strips may be laid either with the lower portions 5 of the projections inflat condition, as shown in Fig. 2, or with such portions bent under in hook-form, as shown in Fig. 3. 1

When the strips are laid flat, the laterally extending spurs of the. portions 5 of each projection will engage under the portions 4- of the adjacent projections of the next underlying strip, and will thus interlock the strips of the several courses.

The strips may also be used with the portions 5 of each projection bent back in hoolrform and inserted under the tops of the reportions 5 is greater than the width of the top of the recesses 3, respectlvely, prevents the butts from being accidentally blown or pulled out ct place.

As shown in Fig. 6, strips of the character waste. by cutting lengthwise a web or sheet of roofing material sufiiciently wide to accommodate two strips widthwise, in such manner as to leave projecting portions l'-5 alternating at either side of the cut, and cutting crosswise, at staggered points, to divide the strips into elements oi desired length having ,their! ends so shaped that when laid end to end,

the contiguous end portions form a recess similar to the recessses 3 between the ad'acent projections 4l-5. Freterably, to facilitate laying, the units consist of strips each having two or more projections but it desired the units may consist of elements each are aid end to end, the contiguous ends form a recess which is similar to the first mentioned recesses.

2. A" prepared roofing' strip having its lower edge formed with alternating projections and recesses, eachprojection consisting of two mutually similar trapezoidalshaped portions disposed one above the other, the projections and recsses being substantially'simllar in size and-shape but reversed in position, the ends of the strips being so shaped that when two of said strips are laid end to end, the ontiguous ends form a recess which is simllar to the firstmentioned recesses.

3' A prepared roofing strip having its lower edge formed with alternating projections and recesses which are substantially similar in shape and size but reversed in po-. sition, each projection consisting of two mutually similar trapezoidal-shaped portions disposed one above the other with the narrow end of the upper portion joiningthe wide end of the lower portion, the ends of the strip being so shaped that when two or said strips are laid end to: end, the contiguous ends form a recess which is similar to the first-mentioned recesses.

two mutually similar trapezoidal-shaped portions disposed one above'the other with the narrow end of the upper portion joining the wide end of the lower portion, the ends of the elements being so shaped that when two of said elements are laid end to end, the contiguous ends form a recess which is similar in size and shape to the projection but reversed in position.

'6. A roof covering comprising a plurality of prepared roofing units laid end to end in overlapping courses, with their lower iedges forming alternating projections and recesses which are mutually similar in size and shape but reversed in position, each projection consistin of two similar trapezoidal-shaped portions disposed one above the other with the narrow end of the upper portion joining the wide end of the lower portion; and with the tips of the wide end of the lower portion of each projection underlying the up er portion of the adjacent pro ections of t e next lower course.
